Abstract
The invention is directed at an improved construction of a combination dump body spreader, for winter road de-icing, having at least one longitudinal conveyor located along one side being fed by a specially braced "L-shaped" pivotally connected conveyor reloading mechanism, operated by two differential displacement hydraulic cylinders. The drive power source of the conveyor features a new easy mount system. The unit is provided with a conveyor reloading mechanism that can be easily disassembled and reassembled from the main structure through a specially designed pivotal connection system, which allows the seasonal replacement, of the conveyor reloading mechanism by an alternate lighter floor panel configuration to reduce the overall tare weight of the unit. The unit is further equipped with a crushing mechanism to regulate the material flow. The conveyor makes use of an elongated open link chain which reduces the risk of corrosion damages to the conveyor drive system.
Description
BACKGROUND OF THE INVENTION
Traditional truck mounted V-shaped Highway maintenance spreaders consisting of a V-shaped box mounted directly over a conveyor system are gradually being replaced by a more flexible, versatile type of truck mounted spreader body.
Traditional application of the Highway maintenance truck is generally subject to the following equipment mounting cycle. In the fall, the conventional dump body intended to haul bulk material is being replaced by a V-type spreader box for aggregate and/or deicing material.
1o After its seasonal winter use, this V-type hopper spreader is removed again in the spring.
Although becoming increasingly more popular because of their better flexibility of application, the new type of combination dump body spreader is still subject to several restrictions based on operational and increased maintenance problems.
The combination dump body spreaders currently available on the market today are provided with a conveyor reloading mechanism that is operated by generally 2 or more hydraulic cylinders that are of identical construction, either nested vertically in the front and rear corner post of the body side opposite the longitudinal conveyor or submounted under the body understructure.
The hydraulic fluid supplied to these hydraulic cylinders is pumped towards each cylinder through a flow divider valve intended to share the flow evenly and equally into each hydraulic cylinder.
Due to uneven load, pressure conditions, design or wear condition, most flow dividers do not precisely share the flow of hydraulic fluid to the cylinders actuating the raising and lowering of the conveyor reloading mechanism, resulting in uneven, jerky operation of the conveyor reloading mechanism. This resulting uneven operation of the conveyor reloading mechanism will make it jam and wedge causing structural damage to the unit and involve costly repairs.

219622T, Combination dump body spreaders currently available on the market today are known to have a heavy tare weight when used as a conventional dump body unit. Further they are provided with a conveyor reloading mechanism, where the pivotally connecting axis (hinge shaft) is continuous along most of the entire length of the pivotal connection making the hinge shaft very difficult to remove and re-install in case the user wishes to replace the conveyor reloading mechanism for servicing or to achieve a seasonal lighter tare weight when the unit needs only to be use as a conventional dump body spreader.
Combination dump body spreaders currently available on the market today are provided with 1o a conveyor drive assembly consisting of the gear reducer, hydraulic motor, main drive shaft, drive sprockets and flange bearings that cannot be removed from the combination dump body spreader without having to damage it seriously because the conveyor drive components are frozen by corrosion on the main drive shaft.
Combination dump body spreaders currently available on the market today do not provide any way to segregate and crush coarse aggregate coming out of the conveyor system which adversely affect the spreading projection pattern of the aggregate being dumped on the rotating spreading disc, thus increasing the amount of de-icing agent required to maintain the road surface.
Combination dump body spreaders currently available on the market today are provided with a conveyor system making use of a conveyor chain consisting of transverse pin connected links very subject to premature wear and freezing due to the corrosive action of snow and ice melting agent mostly hauled with these types of unit.
A combination dump body spreader having at least one longitudinal conveyor located along one of its body side being fed by an adjacent pivotally connected conveyor reloading mechanism generally operated by two or more hydraulic cylinders should be designed to include the following features.

CA 02196227 1999-07-OS . 2 1 g 6 2 2 7 There are a number of features that are important in the design of a combination dump body spreader:
~ A desirable feature is that the displacement extension and retraction strokes of each cylinder ram are precisely kept equal at every stage of the extension or retraction cycling of the cylinder ram.
~ Another desirable feature is that the amount of hydraulic fluid being fed to each of the hydraulic cylinders causing the raising and the lowering of the conveyor reloading mechanism is precisely calibrated on both raising and lowering cycle.
~ A desired feature is that, the pivotally connected conveyor reloading mechanism must at all time operate evenly, regardless of the load distribution being moved towards its adjacent conveyor, that is the hydraulic cylinder components actuating the raising and lowering of the reloading mechanism must at all time work in phase.
~ Another desirable feature is to achieve the above with the least amount of hydraulic components in order to minimize future maintenance.
~ Another desirable feature is that the conveyor reloading mechanism should be easily dismountable from the combination dump body spreader for servicing.
~ Another desirable feature is that the conveyor reloading mechanism should be easily dismountable from the combination dump body spreader for replacement by a lighter type one when the overall tare weight of the unit becomes critical.
~ A further desirable feature is that the entire conveyor drive system is removable as a complete assembly from the combination dump body spreader unit in the least amount of time without damaging any components.
~ It is further desirable that the size of the granular material coming out of the longitudinal conveyor is evenly controlled to achieve a more effective spreading operation and optimize the action of the snow and ice melting agents on the road surface.
~ It is further desirable that the combination dump body spreader is provided with a conveyor system on which the conveyor chain provides a longer life with the least amount of lubrication maintenance.
~ A desirable feature is that the displacement extension and retraction strokes of each cylinder ram are precisely kept equal at every stage of the extension or retraction cycling of the cylinder ram.

SUMMARY OF THE INVENTION
The invention is directed to an improved construction of the combination dump body spreader having at least one longitudinal conveyor located along one of its body side being fed by a conveyor reloading mechanism provided with a specially braced "L-shaped" vertical structure pivotally connected along side of it and generally operated by two differential displacement hydraulic cylinders. The conveyor drive system located at one end of the combination dump body spreader longitudinal conveyor features a slotted mounting to the conveyor structure, a coarse aggregate crusher to regulate material flow at the spreader conveyor discharge. The longitudinal conveyor chain is made with an elongated open link chain. The improvements to the conveyor system are thoroughly adaptable to the traditional hopper type spreader.
One of the aim of the present invention is to provide a combination dump body spreader with a conveyor reloading mechanism operated by two hydraulic cylinders constructed in such a 2o manner so that in the extension mode the volumetric displacement of oil entering the lower chamber of the first cylinder will cause the ram displacement length of the first cylinder along with the volumetric displacement of the hydraulic fluid located in the first cylinder upper chamber, to be pushed in the second cylinder lower chamber. The second cylinder volumetric displacement being dimensioned so that the amount of hydraulic fluid coming from the first cylinder upper chamber will cause the ram of the second cylinder to move the same exact displacement length as the first cylinder ram for a given amount of hydraulic fluid fed in the lower chamber of the first cylinder.
In the retracting mode, the hydraulic fluid enters the upper chamber of the second cylinder 3o causing the piston of the second cylinder to push the hydraulic fluid back into the upper 21 9 6227_ chamber of the first cylinder causing the ram of the first cylinder to move the same exact displacement length as the ram of the second cylinder.
To further assist the stabilizing effect of the differential displacement hydraulic cylinders, two or more diagonal cross braces are adapted to the vertical structural elements of the conveyor reloading mechanism assembly to increase its tortional rigidity.
Another aim of this invention is that the conveyor reloading mechanism of the combination dump body spreader is operated by a multiple cylinder arrangement where the total force and 1o displacement developed by each of the individual cylinder elements is generated by the hydraulic flow and pressure applied to one of the cylinder.
The invention provides a way to eliminate the use of hydraulic fluid divider commonly used to control the cylinder displacements of the conveyor reloading mechanism on combination dump body spreaders.
A further aim of the invention is to provide a new and improved modular matching section pivotal connections for the conveyor reloading mechanism to the combination dump body spreader structure where the two hinge sections can be disassembled and reassembled 2o together through a mechanical fit that does not require the removal of the hinge shaft from the hinge tube assembly but instead the removal and replacement of two very common bolts and lock nut. This aspect of the invention is of most importance to the maintenance of the unit.
Another aim of the invention is that the reloading mechanism with its floor, front angle bracing closure plate, and its specially braced "L-shaped" vertical and supporting structure can be replaced by the proposed floor panel arrangement when the body is to be used as a conventional dump body. The proposed floor panel arrangement tare weight is less than 40%
the weight of conventional conveyor reloading mechanism.

- ~ 21 9 62 27 The complete conveyor drive system including the gear reducer, the hydraulic motor, the main drive shaft, its supporting bearings and the two drive sprockets can be pulled out upon disconnection of the conveyor chain and taken apart from the combination dump body spreader as a complete unit in the minimum amount of time without damaging any components.
The invention includes a rotating crusher agitator consisting of a cross shaft supported by two adjustable bearing. The cross shaft is provided with moving blades or fingers. The assembly can be either self propelled by the traction of the material coming through the conveyor discharge or assisted by the driving force of the conveyor.
An object of the invention is to provide a cross bar type conveyor system where the cross bars are clamped to elongated type pivotless oval shaped chain links which apertures fits into each of the drive sprockets tooth, similar sprockets are used as followers to keep the chain properly aligned. To further assist the tracking of the chain system and allow proper scraping effect to the conveyor cross bars the conveyor floor is provided with two matching section guideways. The round pivotless links offers very minimum contact area thus remains flexible under most corrosive conditions.
